turtlebot/3ea2c30: liveness -> harmless?

[gavanderhoorn]

turtlebot/3ea2c30 is about an env hook (basically a Bash script 'plugin') trying to find a directory which doesn't always exist (as it's a directory from a different package, which isn't listed as a dependency of the package in which the failing env hook is located):

https://github.com/robust-rosin/robust/blob/7e3932c4906a2851d1f84bfd96ecaa58924c9f57/turtlebot/3ea2c30/3ea2c30.bug#L4-L14

This is classified as SOFTWARE:LIVENESS.

However, the net effects of that env hook failing are essentially:

1. an annoying warning on the console every time a user sources their setup.bash (ie: activates a workspace)
2. the TURTLEBOT_MAP_FILE environment variable not getting set

but the base functionality of the package itself (ie: turtlebot_bringup) is not affected. The robot can still be controlled, no software will fail to work, except some other package which might use this variable (some .launch files in turtlebot_navigation).

Do we feel this is sufficient for a LIVENESS label?

Edit: and the env hook also only sets a "sane default".
